Patch details:1. fix warning about implicit declaration for pthreads-w32 routine2. fix warning about unknown %lld/%llu format strings for printf family (replace all occurences of these format strings by corresponding inttypes.h macros)3. fix warning about implicit activation of auto-import which yields runtime 0x00000005 error when built hb.dll is loaded. This is mingw port gcc-4.5 (and later) specific issue and occurs when hb.dll is linked against shared libstdc++ runtime. Please see the known issue section in this release notes. This issue is not fixed in current gcc-4.5 branch.

I also change pthreads-w32 related ifdef guard to SYS_MINGW & PTW32_STATIC_LIB.I think this is more appropriate because pthreads-w32 won't be used in other platforms and the non-portable call forpthreads-w32 isn't needed for shared pthreads-w32(although, HandBrake doesn't use shared pthreads-w32 by default).

The third one is a forgotten hunk at r3200 check-in. If this is not, the change at r3200 is overwritten and takes no effect.I'm sorry for missing it when I pointed it on IRC because I had already made the same change locally so the warning didn't appear.
